Course Introduction：The network protocol used by the Internet is "TCP/IP protocol". TCP/IP refers to Transmission Control Protocol/Internet Protocol, also known as network communication protocol. It is a protocol suite that can realize information transmission between multiple different networks. The TCP/IP transmission protocol stipulates the standards and methods for communication between various parts of the Internet; and, the TCP/IP transmission protocol is two important protocols that ensure the timely and complete transmission of network data information.
